Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful arc. This three-stone semi-set ring in 14K rose gold offers a modern-minimalist frame, where clarity and structure meet quiet confidence.

Crafted in Williamsburg, the band’s warm rose tone complements the marquise’s sharp geometry, while the semi-set design invites your choice of a 10 x 5 mm center stone. The low-profile setting ensures everyday wearability, with a smooth comfort fit that slides easily beneath gloves or alongside stackable bands.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that balance brilliance with sustainability. The three-stone layout adds dimension without bulk, ideal for hands that appreciate refined detail and subtle drama.

Resizing is straightforward, handled in-studio with care to maintain the ring’s clean lines. Whether you visit us in Williamsburg or design online, this semi-set offers a tailored foundation for your unique center stone.
